Things for personal task management. Fantastical for my calendar (iCal/Calendar). Evernote for making notes, lists and anything reference-related. Pocket for storing articles to read later. Dropbox/Google Drive and Droplr for sharing and file-syncing. Font Explorer Pro for font-management. 1Password for password storage. On The Job for time logging (hasn't been updated in awhile but I still use it, I've tried a few but nothing is quite as good still...)

I use Asana for bigger projects that require collaboration and Wunderlist for personal projects. Evernote for research and personal notes.

P.S - Am I the only one frustrated with Asana and Basecamp not having decent apps for mobile ecosystem? Only Trello has really good mobile apps but I find hard to use Trello for the way I use project management systems.

Evernote for me. It seems like an obvious one but the more you use it the greater it becomes. I have a few things on my plate and the different notebooks are superb for putting a solid divide between companies and projects.
